Re: Ported Intake?

Ported means the port or passages in the intake manifold to the heads have been machined out for improved flow and increased capacity. Typically the inside surfaces are smoothed out and the size of the port at the head is matched with the opening of the head.

I'm not familiar with the Edelbrock 2115 manifold or the PCIII manifold that the guys at Cad Company were refering to. I can only guess that the Edelbrock manifold might be a replacement for OEM and possibly Cad Co. took it and improved on it by porting it out? Just a guess.

The big reason is that Eddy just casts the intakes. Castings don't come out perfectly every time. They also want to sell to alot of people, so they want low prices.
Porting takes a fair amount of time (even on just the intake manifold) and Eddy doesn't want to pay people to port each intake by hand, because then the price of the intakes would go up.

Also, when you say 'all their bases covered' they probably do. Where do you want to build power? Porting it probably removes some lowend torque in favor of midrange and higher end torque. The performer intakes are designed to be a stock replacement and make power from idle, so they don't want to hog out the runners too much. BUT, they are aluminum intakes, so they are very easy for those of us who want more power to port out to our tastes.

Re: Ported Intake?

The 2115 is far from a stock replacement manifold. It's no Bulldog, but it's not just there to look pretty and save weight. When was the last time you saw a stock 500 hitting 5500rpm? The 2115 is a good piece for the price but it has distribution problems. Some cyls get more air/fuel than others. CadCo starts off with a 2115 and tries to correct this and to correct any casting problems like flash around the edges. I dunno how well they correct the issues or if it's worth it, but there you go...
